Referring to FIGS. 2 and 3, a data transmission device comprises a first device 110 including a plurality of data output units 117; a second device 120 including a plurality of sensors 127; a first transmission line 4 for transmitting, a clock 111 a generated at a predefined interval by the signal generator 121 of the second device 120, to a first memory 113, such as a shift register, of the first device 110 and a counter 122 of the second device 120 for data transmission between the first device 110 and the second device 120; a second transmission line 5 for transmitting, to the first device 110, any one of sensor data of the second device 120, such as sensor data 0 to sensor data 7 in FIG. 2, corresponding to binary values “000” 21, “001” 22, “010” 23, “011” 24, “100” 25, “101” 26, “110” 27, and “111” 28 according to output signals of the counter 122 of the second device 120, such as output signals Q0 to Q2 from the counter 122 in FIG. 3; and a third transmission line 6 for transmitting the output signal Q2 of the counter 122 at a predefined interval 29-1 or 29-2 (in FIG. 2) of the counter 122 to enable selected sensor data to be transmitted and stored 30 (in FIG. 3) in the first memory 113 so that the selected sensor data is stored 32 (in FIG. 3) in an internal second memory 115, such as storage register, and or is output to another device (not shown).

In the following, descriptions are made with reference to FIGS. 1 and 3 in order to avoid redundancy.

The first device 110 and the second 120 are physically separated and mounted on different locations and there may be access units 131 and 133 to which the first to third transmission lines 4 to 6, between the first device 110 and the second device 120.

The access units 131 and 133 may comprise a first access unit 131 and a second access unit 133. The first access unit 131 may be adjacent to the first device 110 to connect the first to third transmission lines 4 to 6 and the second access unit 133 may be adjacent to the second device 120 to connect the first to third transmission lines 4 to 6.

Also, the first device 110 comprises an oscillator, the signal generator 111 that generates a clock 111 a (in FIG. 3) at a predefined interval and outputs the clock to the counter 122 of the second device 120; and a memory unit 114 that receives data from the second device 120. The memory unit 114 may be a shift register IC.

The memory unit 114 may comprise at least one of the first memory 113 (in FIGS. 1 and 3) and the second memory 115 (in FIGS. 1 and 3).

The first memory 113 may receive/store data output from a multiplexer 124 of the second device 120. The multiplexer 124 may output a value corresponding to a binary output value 21 to 28 (in FIG. 3) by the output signals Q0 to Q2 of the counter 122, such as one of sensor data 0 to sensor data 7.

The second memory 115 may receive and store data 31 and 33 stored in the first memory 113. The first memory 113 may transmit the data 31 and 33 stored through synchronization at a predefined timing to the second memory 115. The predefined timing may be the rising timing 29-1 or 29-2 (in FIG. 3) of the most significant bit output signal Q2 of the output signals of the counter 122.

Sensor data corresponding to the output signal of the counter 122 of the second device 120 is received by and stored in the first memory 113 according to the clock 111 a of the signal generator 111 transmitted by the first transmission line 4.

The second device 120 may comprise the counter 122 and the multiplexer 124.

The counter 122 may output binary other output values “000”, “001”, “010”, “011”, “100”, “101”, “110”, and “111” 21 to 28.

The multiplexer 124 may receive a binary output value from the counter 122 through SEL0 to SEL2 and output sensor data 0 to sensor data 7 corresponding thereto through the second transmission line 5.

As described above, in an embodiment, the counter 122 of the second device 120 operates by the clock 111 a of the signal generator 111 of the first device 110, the multiplexer 124 of the second device 120 selects the sensor data 0 to sensor data 7 of each sensor 127 corresponding to the output signals 21 to 28 (in FIG. 3) of the counter 122 to sequentially outputs selected sensor data 35 (in FIG. 3) and transmits the selected sensor data 35 (in FIG. 3) to the first memory 113 of the first device 110. When the clock 111 a of the signal generator 111 of the first device 110 and a predefined timing (such as a rising timing 29-1 or 29-2 in FIG. 3) of the output signal Q2 of the output signals of the counter 122 of the second device 120 are transmitted by the third transmission line 6, the sensor data 30 (in FIG. 3) transmitted to the first memory 113 is accordingly stored in the second memory 115. That is, at the rising timing of the output signal Q2 of the counter 122 of the second device 120, the data 31 stored in the first memory 113 is stored as the data 32 of the second memory 115 and maintained until the next rising timing of the output signal Q2. Likewise, at the next rising timing of the output signal Q2, the data 33 stored in the first memory 113 is stored as the data 34 of the second memory 115.

For reference, 0-1, 1-1, 2-1, 3-1, 4-1, 5-1, 6-1, and 7-1 of the outputs of the multiplexer 124 mean first sensor data output by eight sensors, respectively, and outputs 0-2, 1-2, 2-2, 3-2, 4-2, 5-2, 6-2, and 7-2 mean second sensor data output by eight sensors, respectively. In addition, R0, R1, R2, R3, R4, R5, R6, and R7 of the shift register 113 mean individual registers of the first memory 113.

In addition, the operation of an embodiment is described.

The clock 111 a of the signal generator 111 of the first device 110 is transmitted to the counter 122 of the second device 120 through the first transmission line 4 and sequentially increases the output values 21 to 28 (in FIG. 3) of the counter 122.

When the outputs 10 to 12 of the counter 122 are input to the multiplexer 124, the multiplexer 124 transmits sensor data 0 to sensor data 7 corresponding to the outputs 10 to 12 of the counter 122 to the first memory 113 of the first device 110 sequentially through the second transmission line 5. For example, when the output value of the counter 122 in FIG. 3 is the binary value “000” 21, the multiplexer 124 outputs sensor data 0, an input value of IN0. Also, when the output value of the counter 122 in FIG. 3 is the binary value “001” 22, the multiplexer 124 outputs sensor data 1, an input value of IN1. In such a manner, the multiplexer 124 outputs sensor data 0 to sensor data 7 according to the output value of the counter 122.

The sensor data 0 to sensor data 7 transmitted in such a manner is stored in the first memory 113 in a shift register IC by the clock 111 a of the signal generator 111 of the first device 110, and as the most significant bit output signal Q2 of the outputs of the counter 122 of the second device 120 is transmitted through the third transmission line 6, the data stored in the first memory 113 is stored in the second memory 115.

The clock 111 a of the signal generator 111 synchronizes the first memory 113 of the first device 110 with the counter 122 of the second device 120. As shown in FIG. 2, the second device 120 may comprise the signal generator 121.

According to the clock 111 a of the signal generator 111, the binary output value of the counter 122 of the second device 120 increases, and sensor data, the output of the multiplexer 124 varying depending thereon is sequentially stored in the first memory 113 in a shift register IC based on the clock 111 a of the signal generator 111 transmitted by the first transmission line 4.

The memory unit 114 may be the shift register IC and comprise the first memory 113 and the second memory 115. The first memory 113 stores sensor data transmitted from the second device 120 according to the clock 111 a of the signal generator 111. The second memory 115 stores the data of the first memory 113 in synchronization with the most significant bit output signal Q2 of the outputs of the counter 122.

The multiplexer 124 sequentially transmits each sensor data to the first device 110 through the second transmission line 5 according to the outputs 10 to 12 of the counter 122.

The counter 122 increases an output according to the clock 111 a of the signal generator 111 transmitted through the first transmission line 4 and each sensor data of the multiplexer 124 is sequentially transmitted to the first device 110 accordingly.

When transmitting data from the second device 120 to the first device 110, a data transmission device according to an embodiment may transmit sensor data by using a less number of transmission lines irrespective of the number of sensors that the second device 120 comprises, as described above. For example, since an embodiment presents an 8-bit device, sensor data is transmitted from eight sensors, but when there is a 16-bit device, it is possible to transmit sensor data from sixteen sensors, even in which case the number of transmission lines do not increase. Sensor data output from sensors that the second device 120 comprises is transmitted to the first device 110 through a transmission line such as a second transmission line 5.

In the data transmission device according to an embodiment, sensors that the second device 120 comprises may be connected to a board of the second device 120 by using a cable. Also, the sensors that the second device 120 comprises may be directly attached to the board of the second device 120 and connected to the multiplexer 124 through a circuit pattern formed on the board without a separate cable. In this case, there is an advantage in that it is possible to further decrease the number of cables.

Also, the first device 110 and the second device 120 may be a main board and a sub board, respectively, and the sensors may be directly mounted on the sub board without a separate cable and connected to the multiplexer 124 through a circuit pattern formed on the sub board. The main board and the sub board are arranged in the housing of a financial device, and data sensed by the sensors is transmitted to the main board through the sub board and processed by the main board.

Also, the sensors of a financial device may comprise at least one of a sensor sensing the opening or closing of a shutter, a sensor sensing the revolution or revolution count of a roller, and a sensor sensing the motion of a guide.

In the data transmission device according to an embodiment, the first device 110 comprises central processing unit (CPU) but the second device 120 does not comprise the CPU. For example, the CPU that the first device 110 comprises may be a device that executes programmed source codes stored in a storage device. Thus, the sensor data output from the sensors that the second device 120 comprises is transmitted to the first device 110 and processed by the CPU that the first device 110 comprises.
